Abstract
Optical trapping provides a non-contact method for the three-dimensional (3D) manipulation of diverse objects. The optical positioning and linking (OPAL) platform used in this study uses an optical trap for object manipulation and a biochemical linking mechanism for building up extended 3D structures. Here we demonstrate the feasibility of the OPAL platform for the fabrication of several large-scale 3D assemblies consisting of hundreds of building blocks. We develop an efficient computer-controlled platform and explore the optimal parameters for the biochemical linking mechanism. Finally, we discuss future applications of the OPAL platform and its viability for nanostructure fabrication.
